CHARLES MARTIN, OF MANCHESTER, IOWA.

VIOLIN.

(To all 'whom itu/may concern.'

The primary object of this invention is to improve the construction, and consequently the tone and expression of violins.

A secondary object is to dispense with the usual sound post in violins.

Vith these objects in view the inventionv1 consists in the* improved construction, arrangement and combination of the parts of an instrument :of the character specified,

which will be hereinafter fully described and afterward specifically claimed.

In order that the construction and operation thereof may be readily comprehended, I have illustrated an approvedembodiment of my invention in the accompanying drawings, and will now proceed to fully describe the same in connection with said drawings,

J f in which Figure 1 represents the top or belly of a violin, the linger board or neck being shown partly broken away and interior parts being shown in dotted lines',

Fig. 2, a sectional View of the instrument taken on the central longitudinal, vertical plane indicated by the broken line 2 2 ofy Fig. 1, and

Fig. 3, a sectional view on the transverse vertical plane indicated by the broken line 3-3 of Fig. 1.

Like reference characters mark the same parts in all of the figures of the drawing.

Referring specifically to the drawing, 5 indicates the top or belly of the instrument,

6 the bottom or back thereof, and 7 ther finger board projecting from the neck ey and belly but I have dispensed with this,y

usual well known part and in lieu thereof n I provide bars 10 and 11 of the form shown plainest in Fig. 2, being, in an ordinary instrument, about 712 inches long, 3g inch thick, and 1 inch wide, although these dimensions may be varied in different instruments as experience, experiment or judgmentmay dictate. y

rThesebars I place under the belly, inside the instrument, in position 'to form an elongated V with the apex toward the neck of the instrument, and glue the ends 12 of the upper edges for the extent of yapproximately half an inch to the under or'inner side of the belly,

Holes 13 and 14: are formed through the` I body of the belly eachpositioned at one side of approximately the center of the area thereof to `lie directly over one of the bars 10 and 11. Within these holes two cylinn drical posts 18 and 19 are placed which rest upon the upper edges of the bars 10 and 11 and project through the holes slightly above the outer face'of the belly and are arranged tofsupport the feet 15 and 16 kof the bridge 17 It is thek purpose of this invention to dispose the holes 13 and 14 at each side of approximately the center of the belly as shown in Fig. 1, where the line 3-3 passes through these holes at a right angle tothe line 2-2 and thus divides the belly into two parts of substantially equal area. By such a division of the surface of the belly each quarter of the instrument would be of prac-k tically the same area, as the posts disposed in the holes lie at equal distances on each side of substantially the exact center of the vsurface as before described.

This arrangement distributes the weight or pressure of the bridge upon somewhat widely separated points in the belly, being they forward and rearward ends of the bars where they are secured to the belly, and

variations may be made `from the specific construction described, without departing from the spirit and scope of the invention. Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent of the United States is:

l. A violin comprising the usual body having belly, back and bridge, provided with holes in the belly, short posts project.-

ing through said holes in position to receive and support the feet of the bridge, and elongated supports for said posts secured to the inner face of said belly.

2. A violin comprising the usual body, having belly, back and bridge, provided With holes in the belly, short posts projecting through said holes in position to receive and support the feet of the bridge, and supports for said posts inside the body, coinprising bars secured to the inside of the belly and passing under said holes.

3. A violin comprising the usual body having belly, back and bridge, provided with holes in the belly, short posts projecting through said holes injposition to receive and support the feet of the bridge, and supports for said posts inside the body coinprising bars secured at their extremities to `the inside of the belly and passing under said holes.

ll. A violin comprising the usual body having belly, back and bridge, provided Copies of this patent may be obtained for having belly, back .afnd bridge,` providedv With vholes in the belly, short posts projecting through said holes iny position to receive and support the feet of the bridge, and supports for'said Vposts inside the body coinprising tivo bars Vsecured at ktheir extremities to the inside of the belly in position to' i'orin an elongated V, with its apex toward the neck of the instrument, and passing undersaid holes.

In testimony whereof I have signed my naine to this specification in the presence of two subscribing Witnesses: y A
